Cone Engineering Touring Dominator Installed

TPuckett · Apr 14, 2021

Greetings from Upstate South Carolina. I've just installed Cone Engineering Touring Dominators to replace the peashooters on my 2016 T100 (Air-cooled). Man Alive! There is such a difference in the music coming out of those pipes
On the first use yesterday, there was some popping on deaccelerating, I'm about to go out and see if going through the cycle of it sitting overnight will make any difference with the ECU.

I have an appointment @ the Triumph dealership in a couple of weeks to check the ECU mapping with the new pipes. The tech @ the dealership said he had never heard of the ECU "learning" to adjust to the reduced back pressure.

Any advice? I have attached a picture

The ecu won't learn you have open pipe's ! The pooping and such is caused by the SAI. That stand's for S secondary A air I injection !
The EU and Vehicle emissions legislation require emissions to meet A Standard that can't be achieved on such a simple engine management system (ecu) so the exhaust is cleaned up by adding fresh oxygen just after the exhaust valves in the cylinder head exhaust Port !
This causes explosive combustion in the header pipe's on closed throttle running , the cue is two fold !! Remove AIS (blocking off works too) and adjustment to fuel mapping , tuneecu can do this at a tune shop (dynomometer tune)
